Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rear-insertion type (shell) generally comprising a hard lower part (shell) of the shoe body on which the torso itself consisting of a front part and a rear part rests.
This is advantageously applied to rear entry type (rear entry type) ski boots.

This rear part of the torso, which can be tilted rearward to allow the skier's foot to be inserted inside the shoe, is usually tilted against or against the front part of the torso, depending on the configuration. It is hinged to the lower part of the shoe body. In all these cases, the coupling means ensure retention in the closed position on the lower part of the skier's legs due to the proximity of the front and rear parts of the torso.

These connecting means were disclosed by the applicant on April 29, 1976.
An anchoring terminal type hooking device surrounding the rear high point of the body and extending parallel to each other, as illustrated and claimed in French Patent No. 345959 filed under and/or by two strands of cable fixed to the front part of the barrel by means of rack-type levers.

Such a connection means is equally applicable to children's ski boots. However, it has been difficult for young skiers to properly close and tighten their uppers with this connection. In fact, when the torso is in the open position and the shoe is being put on, the rear part of the torso (i.e. the rear cover) is tilted backwards, and the tightening lever of the lower part of the leg is It is separated from the rack located on one side of the front part.

For this reason, the two strands of the cable that ensure the closure are no longer held against the shoe, for example by hooking means located on the other side of the torso part, but are free in all directions. It floats and from there it occupies an inappropriate position for a good closure of the shoe. Therefore, careless manual manipulation by a child skier can result in the upper striations of the cable being located inside the rear shroud. In contrast, only the lower filament of the cable occupies the position normally provided in the rear shroud, so that:
This significantly alters the shoe retention status of the wearer's foot.

The present invention aims at 1- eliminating the above-mentioned drawbacks;
In particular, ski shoes for children will be introduced. To this end, one applicant has sought to reduce the height of the upper of the shoe in order to better adapt it to the form of young skiers.

The invention therefore aims to realize a guiding and holding means for a closure and tightening device for the lower leg of the type with cables, which cables can be attached to the target ski, regardless of the height of the upper. Suitable for constant use to ensure proper positioning of the coupling means around the rear cover of the shoe.

On the other hand, the present invention provides guide means for the means for connecting the tightening device in a predetermined position of the shoe, and also allows said connecting means to be disassembled, if necessary, in order to be replaced in case of damage. is also the purpose.

Finally, the invention further provides that, due to the permanent influence of said guiding and holding means around at least one section of the filament of the cable constituting the coupling means, when said closure device is disconnected, this closure Its purpose is to ensure supplementary safety against equipment damage.

To this end, the invention consists of a guiding and holding means for a closing and tightening device which is arranged between two parts of the ski boot so as to be close to each other's legs and/or feet of the skier. The means may be removably clipped across a window provided in at least one wall of the two approximating shoe parts and is located on one side of said wall and is located on one side of said wall. A guiding tunnel is formed in which the coupling means belonging to the closing and tightening device slide freely.

BRIEF DESCRIPTION OF THE DRAWINGS The features of the invention will become apparent from a consideration of the following description given as an embodiment and made with reference to the accompanying drawings.

Referring first to the embodiment of the alpine ski boot shown in FIG. 1, this shoe 1 comprises a shoe body lower part (shell lower part) 2, on which a front part called a sleeve 4 and a rear cover 5 are arranged. A torso 3 consisting of a so-called rear part is attached, at least the tit of these parts being hinged to the shoe body lower part 2.

In the embodiment shown, the rear shroud 5 is mounted pivotably about an axis realized by a hinged rivet 6;
As a result, the rear cover can be pivoted rearwardly, allowing the shoe to be fitted from the rear in an open position (not shown). In the closed position I, the rear cover 5.

It is held against said sleeve 4 by closing and tightening means constituted by an operating lever 7. A flexible support 8 formed by a tension cable 9 is connected to this operating lever. This flexible support 8 is hooked to the other side of the sleeve 4 on an anchoring terminal (not shown) in a known manner. The operating lever 7 itself cooperates with a rack 10 which is mounted integrally with the first side of the sleeve 4. In this way, the wings 8 (i.e. the upper striations 8'' and the lower striations 8'') defining the two striations of the cable are connected to the rear cover 5.
and holds this rear cover in a closed position relative to the sleeve 4.

The upper striation (8') is held across guide means 11 provided in the upper central part of the rear cover 5, so that it can simultaneously slide freely during the tensioning operation of the tensioning means 7, 8, 10; and is maintained in a good closed position along the height of the rear cover 5. Although not shown in Figure 1.

It is also quite possible to consider attaching such a guide means 11 to the lower striation 8'' of the shaft.

As shown in particular in FIGS. 2 and 3, the guide means 11 comprises a kind of saddle key having a generally U-shaped profile in cross-section and the guide means 11 arranged in the wall of the rear cover. The window 13 has a width approximately corresponding to the width of the saddle key.

This window 13 is located approximately in a plane that includes the sleeve 4 and the integrated rack 10, so that the striated portion 31 of the ring,
It enables a good alignment of 3+1, thus ensuring the realization of an optimum tensile state for tightening.

Similarly, in response to an opening movement of the rear shroud 5, when the operating lever 7 is separated from the rack 10, the upper striation 8' is captured in the saddle key 12, in which the striation is connected to the rear shroud. Slide until the maximum opening position is reached.

During opening movements as well as in the surface position of the shoe.

The closing means remains connected to said rear cover 6 without assuming a position different from the position in which said shaft remains connected to said rear cover 5.By means of the guiding and holding means 11 according to the invention, the operating lever 7 The end of the shaft 8, on which the shaft is hooked and secured, is arranged in such a way as to allow a direct and easy torsional movement by the skier (including young skiers), thereby allowing the threaded portion 8' of the shaft to move.

It is possible to present a lever surface to the rack 10 without having to make sure that the rear cover 5 is well placed on the outer surface of the rear cover 5.

In order to be able to anchor the saddle key 12 in the rear cover 5, the two branching parts 14,15 of the U-shaped shaft are each provided with a groove 16, the width of which is as shown in FIG. As shown, it corresponds to the thickness of the wall portion 5' of the rear cover 5. These branches terminate in edges 17, 18 which bear on the inner surface 5'' of the rear shroud wall 5' so that the saddle key 12 is ratcheted into the window 13 disposed therein. The height of the window 13 is ?1ill between the bottom of each groove 16 so that the branch 14.15 is under slight stress.
The saddle key 12 is mounted within this window, which is preferably slightly smaller than the specified dimensions.

Accordingly, the U-shaped contoured opening 19 of said saddle key 12
is directed inside the shell, which allows the assembly of the tensioning means (in this case the cable 9) to be immovable. Note that this tensioning means is applied to the outer surface 5'' of the wall portion 5'.
and the corps bisea of the saddle key 12.
ut6) 20 in a sandwich shape in a free state (see FIGS. 5 and 6). This sliding action of the tensioning means is provided by the fact that the width of the U-shaped opening 19 is, for example, slightly larger than the diameter of the cable 9. For example, in the case of tension means such as strips,
The same dimensional principles apply to cables.

The assembly of the retaining means 11, which is particularly clear from FIGS. 3 to 6, is realized by inserting the saddle key 12 from inside the barrel 5 into the window 13, as indicated by the arrow 21. The upper striated portion 8' is inserted into the opening 19 defined between the U-shaped profiled branches 14, 15 of the saddle key 12, whereas the saddle key not yet ratcheted into the window is inserted into the wall. The upper striated portion 8' appears on the inner surface 5'' side of the portion 5'. In order to be able to be inserted into the saddle key 12 in this manner, the upper striated portion 8' must be provided with a window as shown in FIGS. 3 and 4. In addition, the oblique section 20 of the saddle key 12 allows the filament to be introduced into the window 13 at each branch part 14. The flexibility of .15 makes it easier to reduce the size of the opening 19 by pinching and to allow access between the two.This access of the bifurcation, indicated by arrows 23.24 in FIG. The opening 19 is reduced to dimensions smaller than the dimensions of the cable 9, thereby preventing cable escape during the placement of the saddle key in the window.Finally, the saddle key 12 is placed on the diagonal section 20. 2 laterally arranged insertion chamfers 25.2
It is good to have 5'. This chamfered part for insertion 25.
25' is a vertical side surface 13' of the window 13.

13'' and the side edges 26, 26' of the diagonal section 20, and whose dimension "p" It is equal to the dimensions such as the thickness of the shaped member.

Such a simple and inexpensive device is well suited for rear-entry ski boots with cabled torso closures; It can be similarly adapted to the equipment used. In this case, the shape and dimensions of the guide device according to the invention are also adapted to the shape and dimensions of the strip.

In the same spirit, it is equally possible to provide a ski boot or other sports shoe other than skis with a plurality of these devices, which are also applicable to compositions.

Finally, various modifications can be made to the device and to the shoe described above and shown in the drawings without departing from the scope of the invention.
